Power supply E is accumulator。

Operation principle of the present utility model is: during use; push button S1; after the voltage breakdown diode D1 of accumulator E, relay K is turned on; the contact K-1 adhesive of relay K; circuit self-locking, simultaneously enters battery tension detection guard mode, and pick up A converts the acoustical signal of pickup to the signal of telecommunication; then amplified by V1 and V2 is anti-phase, control IC1, IC2 respectively and drive advance and retreat motor M1 and turning motors M2 work。R1, R2 are the biasing resistors of A, can change receiving sensitivity, i.e. the distance of acoustic control distance。High-frequency bypass capacitor C1 and coupling electric capacity C2 can reduce noise interference, increases acoustic control reliability。IC1 is connected into monostable pattern, and IC2 is connected into trigger mode, and M1, M2 are connected between the outfan of IC1, IC2。

When A does not receive effective sound control signal, V1 ends, V2 turns on, and IC2 is high level because of 2 feet, and making 3 feet is low level, IC2 is low level because of 2,6 feet, making 3 foot output high level, M1 obtains positive current and rotates forward, and toy car moves ahead, now because of the reverse-biased cut-off of D1, thus turning motors M2 no current and do not work；When A receives the command signal of certain frequency and the sound intensity, V1 turns on, and V2 ends。2 feet of IC1 are low level so that it is 3 feet are high level, and IC2 is that high level makes its 3 foot be low level because of 2,6 feet, and M1 obtains negative current reversion, and toy car retreats, and meanwhile, D2 turns on, and M2 obtains negative current (positive current also can) makes toy car turn。After transient state time t, 3 feet of IC1 overturn to low level, and M1 obtains positive current makes toy car continue to move ahead by the direction after turning, and lose electric current because D1 ends M2 and stop turning simultaneously。

Along with the electric discharge of accumulator carries out, its voltage constantly reduces, when its voltage is reduced to under-voltage marginal value; the undertension of accumulator E with breakdown diode D1, therefore relay J dead electricity, its contact K-1 disconnect; reminding user to charge in time, effectively protection accumulator E is not by under-voltage damage。
